In the world of programming, there's a handy trick called memoization
that can make your code faster. It's like having a cheat sheet for
math problems you've already solved.
Memoization works like this: when you run a function with certain inputs, it remembers the result so that if you run the function again with the same inputs, it doesn't have to do the work all over again. It's like storing answers in a secret box for quick access later.
Here's how it works in simple terms: Imagine you have a function that adds two numbers together. Every time you call this function with the same numbers, it does the same calculation. Memoization helps by remembering the result the first time you call the function with those numbers. So, if you call it again with the same numbers, it just gives you the remembered answer instead of recalculating it.
You can set up memoization in JavaScript by creating a special version of your function that stores the results it calculates. Then, when you call the function with the same inputs again, it checks if it already has the answer in its memory. If it does, it just gives you that answer instead of redoing the calculation.
Using memoization can make your code run faster because it avoids doing repetitive work. It's like having a shortcut to get to the answer without going through all the steps again. Just remember, while memoization can speed up certain parts of your code, it's not a magic solution for everything. You still need to be careful about when and how you use it.
In summary, memoization is a simple but powerful technique in JavaScript that helps speed up your code by remembering previous calculations. By understanding and using memoization wisely, you can make your JavaScript programs run more efficiently and smoothly.
